Niche Web Tip - Don't Lose Pages - Redirect
I'm constantly amazed at the number of web pages that go bad. Government, non-profit and commercial websites that seemingly have large budgets often have pages that go missing. It is very frustrating to click on an interesting link and end up at a page that says "404 not found." There is no good reason for this.
At MapCruzin I've tried to make sure that there are no lost pages. The reason I do this is that links exist forever. Who knows how many folks have bookmarked pages or linked to them from websites. Over the 14 years that MapCruzin has been online, I'm sure that there are many thousands.
The first fix, but not the best, is to redirect your "404 not found" to a real web page that will help visitors find what they are looking for. I do this at MapCruzin.com with this 404page.html. Instead of a page that goes nowhere, folks can search the website and hopefully find what they are looking for.
Better yet is to always redirect pages so that visitors never see your 404 page unless, of course, they type a url incorrectly or the link is configured wrong. If you have moved a page, redirect the old to the new. If you have deleted a page, redirect it to a related page.
Here's how I do these two redirects:
To redirect any "404 not found" to a real web page of your own design, first make a page and name it "404page.html." or anything you like. Then create a file named ".htaccess" in the root directory of your website if it does not already exist. The contents of the "htaccess" file should be "ErrorDocument 404 http://www.mapcruzin.com/404page.html." If you already have an ".htaccess" file, add the content to the existing file.
To redirect any webpage, replace the content of the old page with the following:
<HTML>
<HEAD><TITLE>Redirect</TITLE>
<META HTTP-EQUIV="Refresh" CONTENT="0;URL=http://www.mapcruzin.com/">
</HEAD>
</body>
</html>
The "0" after "CONTENT=" denotes the length of time the server will pause on the page - I set this to zero so there is no pause at all. Place your new page url after "CONTENT="0";URL=".
In this example, the page is redirected to http://www.mapcruzin.com, but you can put any url in there that you like.
This should help lower the aggravation level of your visitors and keep them on your website a bit longer. After all, you've made a great deal of effort to create valuable content so it makes sense to take these relatively simple steps to assure that your visitors find it.

myRTK Toxic Maps and Information for Mobile Devices
Back in the 1990s MapCruzin.com created the interactive maps for EDF's Scorecard project. We were contracted to do this because we created the first U.S. based interactive toxic maps on the internet - the Santa Cruz Toxic Release Inventory. Several years ago EDF quit mapping toxics, but scorecard is still a viable source for health effects related to toxics. Since the EDF project, we have continued to map toxics. We did guite a bit of work for the Silicon Valley Toxics Coalition and many projects as part of our interest in bringing Right-to-Know and toxic chemical facility release information to communities in easy-to-use formats.
Some of our outreach efforts include:
Some of our outreach efforts include:
- ToxicRisk.com - Google Maps mashup project based upon EPA Toxic Release Inventory (TRI) data released March 19,2009 and schools in the U.S.
- 2008 Toxic Release Inventory TRI National Analysis.
- Toxic Release Inventory (TRI) 2007 Google Earth Maps.
- 2004 Toxic Release Inventory Maps in ESRI Shapefile Format .
- Interactive 1997 TRI Maps and Data.
- TRI Explorer - Humboldt County Facilities Reporting 2004 Toxic Releases.
- TRI Total Increase 1997 - 1998 & Ranking.
Screenshots from myRTK Toxic Maps and Information for Mobile Devices
Recently EPA released their myRTK application for mobile devices. Here are some screentshots along with brief descriptions. Learn more about myRTK.
myRTK Introductory screen.
My search of "City of Industry, CA" returned this google map.
A click on the list button produced a list of the 29 facilities on the map.
Going back to the original map and zooming out resulted in many more facilities.
Now many more facilities are listed. The list always reflects the facilities show on map.
One way to view information about a facility is to click on the arrow to the right of its name. Doing so results in this screen.
